16、springcloud整合Swagger2构建Restful服务的APIs

Spring Cloud将服务注册到了Eureka上,可以从EurekaUI界面中,看到有哪些服务已经注册到了Eureka Server但是如果想查看当前服务提供了哪些RESTful接口方法的话,就无Eureka Server获取了,而传统的方法是梳理一个接口文档来供开发人员之间来进行交流这种情况下经常会造成文档和代码的不一致性,比如说代码改了,但是接口文档来得及修改等问题,而Swagger2则给我们提供了一套完美的解决方案,下面来看看Swagger2是如何来解决这个问题的。

 

1、 新建项目sc-swagger2,对应的pom.xml文件

 

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

<modelVersion>4.0.0</modelVersion>

 

<groupId>spring-cloud</groupId>

<artifactId>sc-swagger2</artifactId>

<version>0.0.1-SNAPSHOT</version>

<packaging>jar</packaging>

 

<name>sc-swagger2</name>

<url>http://maven.apache.org</url>

 

<parent>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-parent</artifactId>

<version>2.0.4.RELEASE</version>

</parent>

 

<dependencyManagement>

<dependencies>

<dependency>

<groupId>org.springframework.cloud</groupId>

<artifactId>spring-cloud-dependencies</artifactId>

<version>Finchley.RELEASE</version>

<type>pom</type>

<scope>import</scope>

</dependency>

 

</dependencies>

</dependencyManagement>

 

<properties>

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<maven.compiler.source>1.8</maven.compiler.source>

<maven.compiler.target>1.8</maven.compiler.target>

</properties>

 

<dependencies>

 

<dependency>

<groupId>io.springfox</groupId>

<artifactId>springfox-swagger2</artifactId>

<version>2.9.2</version>

</dependency>

 

<dependency>

<groupId>io.springfox</groupId>

<artifactId>springfox-swagger-ui</artifactId>

<version>2.9.2</version>

</dependency>

 

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

</dependency>

</dependencies>

</project>

 

 

 

2、 新建springboot启动类

 

package sc.swagger2;

 

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.SpringBootApplication;

 

@SpringBootApplication

public class Swagger2Application {

 

public static void main(String[] args) {

SpringApplication.run(Swagger2Application.class, args);

}

 

}

 

 

3、 新建Swagger2配置类

 

package sc.swagger2.config;

 

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

 

import springfox.documentation.builders.ApiInfoBuilder;

import springfox.documentation.builders.PathSelectors;

import springfox.documentation.builders.RequestHandlerSelectors;

import springfox.documentation.service.ApiInfo;

import springfox.documentation.service.Contact;

import springfox.documentation.spi.DocumentationType;

import springfox.documentation.spring.web.plugins.Docket;

import springfox.documentation.swagger2.annotations.EnableSwagger2;

 

@Configuration

@EnableSwagger2

public class Swagger2Config {

 

@Bean

    public Docket createRestApi() {

        return new Docket(DocumentationType.SWAGGER_2)

                .apiInfo(apiInfo())

                .select()

                .apis(RequestHandlerSelectors.basePackage("sc.swagger2"))

                .paths(PathSelectors.any())

                .build();

    }

 

    private ApiInfo apiInfo() {

        return new ApiInfoBuilder()

                .title("Spring Boot中使用Swagger2构建RESTful APIs")

                .description("更多Spring Boot相关文章请关注: JAVA乐园  公众号")

                .termsOfServiceUrl("https://edu.csdn.net/lecturer/995")

                .contact(new Contact("huangjinjin", //

                 "https://edu.csdn.net/lecturer/995",//

                 "happyhuangjinjin@sina.com"))

                .version("1.0")

                .build();

    }

 

 

}

 

 

4、 新建一个模拟的Controller

 

package sc.swagger2.controller;

 

import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

 

import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.DeleteMapping;

import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.PostMapping;

import org.springframework.web.bind.annotation.PutMapping;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.ResponseBody;

 

import io.swagger.annotations.Api;

import io.swagger.annotations.ApiImplicitParam;

import io.swagger.annotations.ApiImplicitParams;

import io.swagger.annotations.ApiOperation;

import io.swagger.annotations.ApiResponse;

import io.swagger.annotations.ApiResponses;

import sc.swagger2.model.User;

 

@Api(value="用户管理")

@Controller

public class UserController {

 

@ApiResponses({ @ApiResponse(code = 000000, message = "操作成功"),

@ApiResponse(code = 000001, message = "服务器内部异常") })

@GetMapping(value = "/feign/user/getUser/{id}")

@ResponseBody

@ApiOperation(value = "获取根据Id用户信息",response = User.class)

@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long",example="100")

public Map<String, Object> getUser(@PathVariable Long id) {

Map<String, Object> result = new HashMap<String, Object>();

result.put("code", "000000");

result.put("msg", "success");

User u = new User();

u.setId(1L);

u.setAge(23);

u.setUserName("huangjinjin");

u.setPosition("cto");

result.put("body", u);

return result;

}

 

@ApiResponses({ @ApiResponse(code = 000000, message = "操作成功"),

@ApiResponse(code = 000001, message = "服务器内部异常") })

@RequestMapping(value = "/feign/user/listUser", method = RequestMethod.GET)

@ResponseBody

@ApiOperation(value = "获取用户列表")

public Map<String, Object> listUser() {

Map<String, Object> result = new HashMap<String, Object>();

result.put("code", "000000");

result.put("msg", "success");

User u = new User();

u.setId(1L);

u.setAge(23);

u.setUserName("huangjinjin");

u.setPosition("cto");

List<User> list = new ArrayList<User>();

list.add(u);

result.put("body", list);

return result;

}

 

@ApiResponses({ @ApiResponse(code = 000000, message = "操作成功"),

@ApiResponse(code = 000001, message = "服务器内部异常") })

@PostMapping(value = "/feign/user/addUser")

@ResponseBody

@ApiOperation(value = "添加用户", notes = "根据User对象创建用户")

@ApiImplicitParams({ @ApiImplicitParam(name = "userName", value = "用户名", required = true, dataType = "String"),

@ApiImplicitParam(name = "age", value = "年龄", required = true, dataType = "String"),

@ApiImplicitParam(name = "position", value = "职位", required = true, dataType = "String"),

@ApiImplicitParam(name = "id", value = "用户ID", required = false, dataType = "Long",example="100")})

public Map<String, Object> addUser(User user) {

Map<String, Object> result = new HashMap<String, Object>();

result.put("code", "000000");

result.put("msg", "success");

result.put("body", 1);

return result;

}

 

@ApiResponses({ @ApiResponse(code = 000000, message = "操作成功"),

@ApiResponse(code = 000001, message = "服务器内部异常") })

@ApiOperation(value = "更新用户")

@PutMapping(value = "/feign/user/updateUser")

@ResponseBody

@ApiImplicitParams({ @ApiImplicitParam(name = "userName", value = "用户名", required = true, dataType = "String"),

@ApiImplicitParam(name = "age", value = "年龄", required = true, dataType = "String"),

@ApiImplicitParam(name = "position", value = "职位", required = true, dataType = "String"),

@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long", example="100")})

public Map<String, Object> updateUser(User user) {

Map<String, Object> result = new HashMap<String, Object>();

result.put("code", "000000");

result.put("msg", "success");

result.put("body", 1);

return result;

}

 

@ApiResponses({ @ApiResponse(code = 000000, message = "操作成功"),

@ApiResponse(code = 000001, message = "服务器内部异常") })

@DeleteMapping(value = "/feign/user/deleteUser/{id}")

@ResponseBody

@ApiOperation(value = "删除用户")

@ApiImplicitParam(name = "id", value = "用户ID", required = true, dataType = "Long",example="100")

public Map<String, Object> deleteUser(@PathVariable Long id) {

Map<String, Object> result = new HashMap<String, Object>();

result.put("code", "000000");

result.put("msg", "success");

result.put("body", 1);

return result;

}

 

}

 

 

 

 

5、 新建User模型类

 

package sc.swagger2.model;

 

import java.io.Serializable;

 

import io.swagger.annotations.ApiModel;

import io.swagger.annotations.ApiModelProperty;

 

@ApiModel

public class User implements Serializable {

 

private static final long serialVersionUID = 4639927446947303736L;

 

@ApiModelProperty(name="id", dataType="Long", value="主键ID")

private Long id;

 

@ApiModelProperty(name="userName", dataType="String", value="姓名", required=true)

private String userName;

 

@ApiModelProperty(name="age", dataType="String", value="年龄", required=true)

private Integer age;

 

@ApiModelProperty(name="position", dataType="String", value="职位")

private String position;

 

public String getUserName() {

return userName;

}

 

public void setUserName(String userName) {

this.userName = userName;

}

 

public Integer getAge() {

return age;

}

 

public void setAge(Integer age) {

this.age = age;

}

 

public String getPosition() {

return position;

}

 

public void setPosition(String position) {

this.position = position;

}

 

public Long getId() {

return id;

}

 

public void setId(Long id) {

this.id = id;

}

 

}

 

 

6、 启动sc-swagger2项目,并验证是否启动成功

方式一:查看日志

 

 

 

方式二:访问地址

http://127.0.0.1:9092/swagger-ui.html

 

 

 

或者访问http://localhost:9092/v2/api-docs

 

 

 

 

7、 在界面http://127.0.0.1:9092/swagger-ui.html点击【user-controller】可以看到所有的接口,同时也可以在界面上进行接口调用调试
